Abstract
What is already known on this topic?Hydrogen peroxide sterilizeation is widely used for luminal devices. However, the low penetrability of the sterilant is of major concern.What is added by this report?This report investigated the effective sterilization of low-temperature hydrogen peroxide gas plasma sterilizers and compared the applicability of different biological monitoring methods based on medical luminal devices.What are the implications for public health practice?It is recommended to use a biological process challenge device for monitoring the sterilization of luminal devices with low-temperature hydrogen peroxide gas plasma sterilizers.
Highlights
With minimally invasive techniques improving, various types of medical luminal devices are widely used in surgeries
This study aimed to investigate the effective sterilization of low-temperature hydrogen peroxide gas plasma sterilizers and to explore the applicability of different biological monitoring methods based on medical luminal devices
Basic information of low-temperature hydrogen peroxide gas plasma sterilizers in 58 hospitals across 22 provinciallevel administrative divisions (PLADs) was investigated, and these sterilizers were tested with biological process challenge devices (PCD) and normal biological indicators (BI) at the same time to test the effectiveness of sterilization and to compare the monitoring results
Summary
This report investigated the effective sterilization of low-temperature hydrogen peroxide gas plasma sterilizers and compared the applicability of different biological monitoring methods based on medical luminal devices. This study aimed to investigate the effective sterilization of low-temperature hydrogen peroxide gas plasma sterilizers and to explore the applicability of different biological monitoring methods based on medical luminal devices. To understand the effective sterilization of luminal devices sterilized by low-temperature hydrogen peroxide gas plasma sterilizers, a survey was carried out as part of “National Surveillance Program for Hospital Disinfection and Sterilization Effects and Nosocomial Infection” conducted by China CDC. This survey included 58 sentinel hospitals across 22 PLADs of China. A positive control culture being observed with a CCDC Weekly / Vol 3 / No 29
